RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application No. 61/359,638, filed Jun. 29, 2010, the entire content of which is hereby incorporated by reference.

BACKGROUND

The present invention relates to riminophenazines having heteroaromatic substitutions, to their preparation, and to their use as drugs for treating Mycobacterium tuberculosis and other microbial infections, either alone or in combination with other anti-infective treatments.

Mycobacterium tuberculosis (“M.tb”) is the causative agent of tuberculosis (“TB”), a devastating infectious disease. It is estimated that about 2 million TB patients die each year globally. There are urgent needs for new drugs to fight the increasing threat of tuberculosis.

Current first-line drug therapy for tuberculosis is long and complex, involving multidrug combinations (usually isoniazid, rifampin, pyrazinamide and ethambutol) given daily for 6 to 9 months. Furthermore, these drugs are relatively ineffective against the resistant form of the disease and difficult to use to treat TB/HIV co-infected patients due to drug-drug interactions (Ma et al., 2009).

Clofazimine was first reported in 1957 by Barry and was found to possess potent antituberculosis activity (Barry, V. C., 1957). It demonstrated in vivo anti-TB activity in mice and hamsters, but failed to show efficacy in guinea pig and monkey models. The major drawbacks of clofazimine are skin discoloration, high fat tissue distribution, and very long half-life (70 days). New riminophenazine analogues have been synthesized to identify compounds with improved activity, lower side effects, and better solubility. Among those compounds, B4154 and B4157 showed improved in vitro activity (V. M. Reddy, 1996).

The structures of clofazimine, B4154, and B4157 are shown below.

One of the major advantages of the riminophenazine class is their low frequency for resistance development. They are highly potent against various forms of drug-resistant TB. New and improved riminophenazines could potentially contribute to the treatment of both drug-susceptible and drug-resistant tuberculosis.

SUMMARY

The current invention pertains to riminophenazines with 2-(heteroaryl)amino substituents, their methods of preparation, and their use as treatments for tuberculosis and other microbial infections.

In the current riminophenazine molecules, the phenylamino group attached to the 2-position of the riminophenazine core can be replaced by a heteroarylamino group as shown in general formula (I) below.

In this structure, R₁, R₂, R₃ and R₄ can be a variety of substituents. The heteroaromatic ring represents a nitrogen-containing heteroaromatic group. It can be substituted or non-substituted pyridyl wherein X═N and Y═Z═CH, or it can be pyrimidyl wherein X═Y═N and Z═CH, or it can be pyrazinyl wherein X═Z═N and Y═CH. The most preferred compounds include a group of riminophenazines with the 2-phenylamino group replaced by a 2-(3-pyridyl)amino substitution.

The synthesis of riminophenazines of formula (I) follows a modified synthetic procedure reported in U.S. Pat. No. 3,499,899. For example riminophenazines with 2-(3-pyridyl)amino substitutions can be prepared by the following route: 1,5-Difluoro-2,4-dinitrobenzene (DFDNB) was used to ensure easier substitution of the two fluoro by amines, as shown in FIG. 1. The synthesis is started with 1-fluoro-2-nitrobenzene and anilines. The reaction mixture is then heated at 180-190° C. to give 1-anilino-2-nitrobenzene. After reduction of the nitro group, it is coupled with 1,5-difluoro-2,4-dinitrobenzene and then the second fluoro is replaced by 3-aminopyridines. The two nitro groups are reduced either by Zn/acetic acid or by catalytic hydrogenation over Pd—C. After reduction, the tetra-amino compound (without isolation) is stirred and oxidized by air to form the corresponding riminophenazine. The imino group is further derivatized by different aliphatic and heteroaliphatic amines to give the final products. A general representation of the 2-N-(3-pyridyl)-riminophenazines is shown as general formula (II) below.

In this representation shown as general formula (II), R₁ can be H, alkyl, alkoxyl, cycloalkyl, heterocycloalkyl, Cl, F, Br, CF₃, OCH₃, OCF₃, SCH₃, SOCH₃, or a combination of any two or three of them, the same or different. R₃ can be H, alkyl, alkoxyl, cycloalkyl, heterocycloalkyl, halo (F, Cl, Br), NAc, or a combination of any two or three of them, the same or different. R₄ can be H, halo (Cl, Br, F), alkyl, alkoxyl, or mono-, di-, or cycloalkylamino with or without an additional O, S or NR′ in the ring, where R′ is an alkyl or substituted alkyl group; and R₂ can be alkyl, cycloalkyl, substituted alkyl or substituted cycloalkyl; cycloalkyl herein could have an additional O, S, or NR′ in the ring, where R′ is as defined above. A “substituted alkyl or cycloalkyl” is defined as alkyl or cycloalkyl substituted by the groups selected from H, alkyl, alkyoxy, halo, or mono-, di- or cycloalkylamino.

The anti-tuberculosis activity of the compounds was tested against H37Rv strains both in vitro and in vivo. In the in vitro assay, most of the compounds in this class showed equal or better activity when compared with clofazimine, rifampicin, or isoniazid.

BRIEF DESCRIPTION OF THE DRAWINGS

The riminophenazines with 2-(heteroaryl)amino substituents may occur in different geometric and enantiomeric forms, and both pure forms and mixtures of these separate isomers are included in the scope of this invention, as well as any physiologically functional or pharmacologically acceptable salt derivatives or prodrugs thereof. Production of these alternate forms would be well within the capabilities of one skilled in the art.

The current invention also pertains to methods of prevention or therapy for microbial infections, such as Mycobacterium tuberculosis, including the step of administering a riminophenazine with 2-(heteroaryl)amino substituents.

In another aspect of the present invention there is provided a pharmaceutical composition including a therapeutically effective amount of a riminophenazine with 2-(heteroaryl)amino substituents as defined above and a pharmaceutically acceptable excipient, adjuvant, carrier, buffer or stabiliser. A “therapeutically effective amount” is to be understood as an amount of a riminophenazine with 2-(heteroaryl)amino substituents that is sufficient to show antibacterial or antimicrobial effects. The actual amount, rate and time-course of administration will depend on the nature and severity of the disease being treated. Prescription of treatment is within the responsibility of general practitioners and other medical doctors. The pharmaceutically acceptable excipient, adjuvant, carrier, buffer or stabiliser should be non-toxic and should not interfere with the efficacy of the active ingredient. The precise nature of the carrier or other material will depend on the route of administration, which may be oral, or by injection, such as cutaneous, subcutaneous, or intravenous injection, or by dry powder inhaler.

Pharmaceutical compositions for oral administration may be in tablet, capsule, powder or liquid form. A tablet may comprise a solid carrier or an adjuvant. Liquid pharmaceutical compositions generally comprise a liquid carrier such as water, petroleum, animal or vegetable oils, mineral oil or synthetic oil. Physiological saline solution, dextrose or other saccharide solution or glycols such as ethylene glycol, propylene glycol or polyethylene glycol may be included. A capsule may comprise a solid carrier such as gelatin. For intravenous, cutaneous or subcutaneous injection, the active ingredient will be in the form of a parenterally acceptable aqueous solution which is pyrogen-free and has a suitable pH, isotonicity and stability. Those of relevant skill in the art are well able to prepare suitable solutions using, for example, isotonic vehicles such as sodium chloride solution, Ringer's solution, or lactated Ringer's solution. Preservatives, stabilisers, buffers, antioxidants and/or other additives may be included as required.

The pharmaceutical composition can further comprise one or more additional anti-infective treatments. These anti-infective treatments can be any suitable treatment available commercially or from other sources that are known to effectively prevent or treat microbial infections, such as Mycobacterium tuberculosis.

In another aspect, there is provided the use in the manufacture of a medicament of a therapeutically effective amount of a riminophenazine with 2-(heteroaryl)amino substituents as defined above for administration to a subject. There is also provided a method of making riminophenazines with 2-(heteroaryl)amino substituents.

The term “pharmacologically acceptable salt” used throughout the specification is to be taken as meaning any acid or base derived salt formed from hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic, isoethonic acids and the like, and potassium carbonate, sodium or potassium hydroxide, ammonia, triethylamine, triethanolamine and the like.

The term “prodrug” means a pharmacological substance that is administered in an inactive, or significantly less active, form. Once administered, the prodrug is metabolised in vivo into an active metabolite.

The term “therapeutically effective amount” means a nontoxic but sufficient amount of the drug to provide the desired therapeutic effect. The amount that is “effective” will vary from subject to subject, depending on the age and general condition of the individual, the particular concentration and composition being administered, and the like. Thus, it is not always possible to specify an exact effective amount. However, an appropriate effective amount in any individual case may be determined by one of ordinary skill in the art using routine experimentation. Furthermore, the effective amount is the concentration that is within a range sufficient to permit ready application of the formulation so as to deliver an amount of the drug that is within a therapeutically effective range.

Some preferred examples of the riminophenazines with 2-(3-pyridyl)amino substituents include compounds having the following structures:

Further aspects of the present invention will become apparent from the following description given by way of example only and with reference to the accompanying synthetic schemes.

Example 1 General Synthetic Methods

General procedures for the preparation of 5-(4-chlorophenyl)-3-(1 methylethyl)imino-2-(3-pyridyl)amino-3,5-dihydrophenazine (TBI-416), or the current riminophenazine compounds, are provided below.

Step A: 2-(4-chloroanilino)-nitrobenzene. A mixture of 2-fluoro-nitrobenzene (33.7 g), 4-chloroaniline (61.0 g) and anhydrous potassium fluoride (13.9 g) was stirred at 180° C. for 10 h. After being cooled to rt, 3 M HCl was added and the mixture was stirred at 100° C. for 30 min. Then cooled to rt, filtered by suction, washed with water to give a brown solid. The solid was dissolved in CH₂Cl₂ and filtered through a thin pad of silica gel, washed with CH₂Cl₂. The filtrate was concentrated to dryness, and the residue was recrystallized with 95% ethanol to give 57.0 g of orange solid.

Step B: 2-(4-chloroanilino)-aniline. To a solution of 2-(4-chloroanilino)-nitrobenzene (57.0 g) in CH₂Cl₂ (40 mL) was added AcOH (90 mL), then Zn (105 g) was added in small portions. After Zn was added, the color of the mixture became light green, filtered by suction, washed with CH₂Cl₂. The filtrate was concentrated to dryness. Water was added, filtered, and washed with water to give a brown solid. This solid was used directly in the next step without further purification.

Step C: 1-[2-(4-chloroanilino)anilino]-3-fluoro-4,6-dinitrobenzene. The solid from step B was added to a solution of 1,3-difluoro-4,6-dinitrobenzene (46 g) in methanol (200 L), then triethylamine (31.4 mL) was added, and stirred at rt for 4 h. The reaction mixture was filtered, and the cake was washed with methanol to give 80.6 g of red solid.

Step D: 1-[2-(4-chloroanilino)anilino]-3-(3-pyridyl)amino-4,6-dinitrobenzene, shown below.

A mixture of 1-[2-(4-chloroanilino)anilino]-3-fluoro-4,6-dinitrobenzene (40.3 g), 3-aminopyridine (14.12 g), triethylamine (14 mL) and THF (200 mL) was heated to reflux for 28 h. then about 150 mL of THF was distilled out. To the residue was added CH₂Cl₂, the solid was filtered, and washed with CH₂Cl₂ to give 31.2 g of red solid. ¹H NMR (300 MHz, DMSO-d₆) δ: 9.72 (s, 1H), 9.50 (s, 1H), 9.00 (s, 1H), 8.40-8.37 (m, 2H), 7.77 (s, 1H), 7.63-7.59 (m, 1H), 7.37-7.33 (m, 1H), 7.21-7.09 (m, 5H), 6.92-6.83 (m, 1H), 6.82-6.78 (m, 2H), 5.92 (s, 1H); ESI-MS (m/z): 477 (M+H⁺).

Step E: 5-(4-chlorophenyl)-3-imino-2-(3-pyridyl)amino-3,5-dihydrophenazine, shown below.

Method A. To a suspension of 1-[2-(4-chloroanilino)anilino]-3-(3-pyridyl)amino-4,6-dinitrobenzene (28.6 g) in AcOH (150 mL) was added Zn powder (69 g) in small portions. After Zn was added, the color of the mixture became light green. The mixture was filtered, washed with AcOH and methanol. The filtrate was concentrated to dryness, water and ammonia was added. After being filtered, the cake was washed with water to give a dark solid. The solid was dissolved in methanol and CH₂Cl₂, stirred at rt in contact with air overnight. The solution was concentrated to a small volume, and filtered, washed with methanol to give 23.1 g of dark solid. ¹H NMR (300 MHz, CDCl₃) δ: 8.63 (d, J=2.7 Hz, 1H), 8.37 (dd, J=4.8 Hz, 1.2 Hz, 1H), 7.81-7.70 (m, 4H), 7.34-7.28 (m, 3H), 7.24-7.18 (m, 2H), 6.94 (s, 1H), 6.54-6.51 (m, 1H), 5.23 (s, 1H). Method B. 9.49 g (21 mmol) of 1-[2-(4-chloroanilino)anilino]-3-(3-pyridyl)amino-4,6-dinitrobenzene was suspended in 100 ml of anhydrous methanol. The mixture was hydrogenation with 0.97 g of 10% Pd—C at 45 psi. Then the Pd—C was removed by filtration. The filtrate was opened in the air and stirred at r.t. over night. The solid separated was filtered out to give the title compound 4.83 g.

Step F: 5-(4-chlorophenyl)-3-(1-methylethyl)imino-2-(3-pyridyl)amino-3,5-dihydrophenazine, shown below.

Step A: 2-(4-chloroanilino)-nitrobenzene. A mixture of 2-fluoro-nitrobenzene (33.7 g), 4-chloroaniline (61.0 g) and anhydrous potassium fluoride (13.9 g) was stirred at 180° C. for 10 h. After being cooled to rt, 3 M HCl was added and the mixture was stirred at 100° C. for 30 min. Then cooled to rt, filtered by suction, washed with water to give a brown solid. The solid was dissolved in CH₂Cl₂ and filtered through a thin pad of silica gel, washed with CH₂Cl₂. The filtrate was concentrated to dryness, and the residue was recrystallized with 95% ethanol to give 57.0 g of orange solid.

Step B: 2-(4-chloroanilino)-aniline. To a solution of 2-(4-chloroanilino)-nitrobenzene (57.0 g) in CH₂Cl₂ (40 mL) was added AcOH (90 mL), then Zn powder (105 g) was added in small portions. After Zn powder was added, the color of the mixture became light green, filtered by suction, washed with CH₂Cl₂. The filtrate was concentrated to dryness. Water was added, filtered, and washed with water to give a brown solid. This solid was used directly in the next step without further purification.

Method B: 8.40 g (21 mmol) of 1-[2-(4-chloroanilino)-anilino]-3-amino-4,6-dinitrobenzene was suspended in 100 mL of anhydrous methanol. The mixture was hydrogenation with 0.97 g of 10% Pd—C at 45 psi. Then the Pd—C was removed by filtration. The filtrate was stirred at rt in contact with air overnight. The solid separated was filtered out to give the title compound 3.90 g.

Step F: 5-(4-chlorophenyl)-3-(1-methylethyl)imino-2-amino-3,5-dihydrophenazine, shown below.

To a sealed bomb was added 5-(4-chlorophenyl)-3-imino-2-amino-3,5-dihydro-phenazine (18.6 g), isopropylamine (99.4 mL) and dioxane (120 mL). The mixture was stirred at 110° C. in the bomb for 24 h. After being cooled to rt, water was added, suction filtered, washed with water to give a dark solid. The solid was purified by flash column chromatography (EtOAc/hexane 1:2) to give 5.6 g of red solid. ¹H NMR (300 MHz, DMSO-d₆) δ: 7.84 (2H, d, J=8.4 Hz), 7.59 (1H, m), 7.55 (2H, d, J=8.4 Hz), 7.14 (2H, m), 6.39 (3H, m), 6.27 (1H, s), 5.11 (1H, s), 3.29 (1H, m), 0.98 (6H, d, J=6.3 Hz).

Example 2 In Vitro Assay for Antimicrobial Susceptibility

Antimicrobial susceptibility testing was performed in 96-well microplates. Initial drug dilutions (6.4 mg/ml) were prepared in dimethyl sulfoxide, and subsequent two-fold dilutions were performed in 0.1 ml of 7H9 in the microplates. The final drug concentrations were about 0.008 μg/ml. Every concentration of test compounds was added to two wells. Control wells consisted of bacteria and positive drug (Clofazimine). Plates were incubated at 37° C. The final bacterial titers were 1×10⁶ CFU/ml for H₃₇Rv. Starting at day 7 of incubation, 20 μl of 10× Alamar blue solution and 12.5 μl of 20% Tween 80 were added to each well and the plates were reincubated at 37° C. Wells were observed at 24 h and the colors of all were recorded. Visual MICs were defined as the lowest of drug that prevented a color change from blue to pink. Fluorescence was measured in a microplate fluorometer in bottom-reading mode with excitation at 530 nm and emission at 590 nm. For fluorometric MICs, the lowest drug concentration effecting an inhibition of ≧90% was considered the MIC. The results are shown Table 1 and 2 above.

Example 3 In Vivo Testing

Male BALB/c mice (18˜20 g) were infected intravenously with 0.2 ml portions containing 1×10⁵ CFU of H₃₇Rv. One day after the infection, four mice were sacrificed and the numbers of CFU in the spleens and lungs were determined. Organs were removed and homogenized in Middlebrook 7H9 broth. To enumerate CFU, appropriate dilutions of the homogenates were plated onto Middlebrook 7H10 agar and colonies were counted after 3 to 4 weeks of incubation at 37° C. The remaining mice were allocated either to untreated groups or to various drug treated groups (six mice per group). The dose of every test compound was 20 mg/kg. The positive control groups were treated by isoniazid and clofazimine. The test compounds and clofazimine were administered by gavage 5 times weekly. Untreated mice were administered by gavage with CMC. Thirty days postinfection, both untreated and treated mice were sacrificed and lung tissue CFU counts were determined. The significance of the CFU count and organ weight difference was assessed by a two-tailed Student t test. P≦0.01 was considered significant. The results of twelve exemplary compounds are shown Table 3 below.
